Subject: [PATCH v2 0/3] Add settle time support to iio-mux
Date: Thu, 7 Oct 2021 15:46:38 +0200 [thread overview]
Message-ID: <20211007134641.13417-1-vincent.whitchurch@axis.com> (raw)
On one of our boards we use gpio-mux with iio-mux to read voltages using an ADC
from a few different channels, and on this board the input voltage needs some
time to stabilize after a switch of the mux.
This series add devicetree and driver support for this kind of hardware which
requries a settle time after muxing.
v1 -> v2:
- Move property support to iio-mux and delay handling to mux core as suggested
by Peter.
v1: https://lore.kernel.org/all/20211004153640.20650-1-vincent.whitchurch@axis.com/

mux: add support for delay after muxing
dt-bindings: iio: io-channel-mux: Add property for settle time
iio: multiplexer: iio-mux: Support settle-time-us property
